The OP asked a legitimate question and one I asked on this same forum many years ago when I purchased my first motor home. Why people feel compelled to respond with a 50% discount suggestion is beyond my comprehension.
A fifty percent discount on a new current year Tiffin is not a reasonable offer nor would it be reasonable for a new year old unit. As a salesman, I would walk away from a customer that seriously started with those numbers and consider them to be a waste of time.
A good question has been asked and deserves a reasonable response corresponding to real world purchases and or offers to sell from dealers.
